Agrostis kunmingensis

HABIT Perennial; caespitose. Rhizomes elongated. Culms geniculately ascending; 35–70(–100) cm long; 1–2.6 mm diam.; 3–7 -noded. Leaf-sheaths smooth. Ligule an eciliate membrane; 2.5–4 mm long; scaberulous on abaxial surface; obtuse. Leaf-blades flat, or convolute; 10–16 cm long; 2.5–4 mm wide. Leaf-blade surface scaberulous; rough on both sides. Leaf-blade apex acuminate.

INFLORESCENCE Inflorescence a panicle.

Panicle open; lanceolate, or ovate; 10–20(–25) cm long. Primary panicle branches ascending; 2–6 -nate; whorled at most nodes; 7–12 cm long. Panicle branches scaberulous.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate, or oblong; laterally compressed; 2.5–3.2 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent. Floret callus hairs 0.3 mm long.

GLUMES Glumes persistent; similar; exceeding apex of florets; firmer than fertile lemma; shiny; gaping. Lower glume lanceolate; 1 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein scaberulous. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 2.5–3.2 mm long; 1.5 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume primary vein scaberulous. Upper glume lateral veins absent. Upper glume apex acute.

FLORETS Fertile lemma oblong, or ovate; 1.6–2.1 mm long; hyaline; without keel; 4–5 -veined. Lemma lateral veins prominent. Lemma surface scaberulous; rough above. Lemma apex truncate; muticous, or awned; 1 -awned. Principal lemma awn dorsal; arising 0.5–0.66 way up back of lemma; straight; 1 mm long overall. Palea 0.2–0.5 mm long; 0.15–0.3 length of lemma; hyaline; 2 -veined.

FLOWER Anthers 3; 1–1.5 mm long.

DISTRIBUTION Asia-temperate: China.
